3 Claims. (Cl. 164-73) My invention relates to cutting and feedingdevices and more particularly to a device for cutting sheets from a rollof paper or thelike and feeding the cut sheets to a wrapping machine.

The prime object of my invention is to provide a device that feeds paperof the correct predetermined length,

cuts it and transfers it to a wrapping machine.

Another object of my invention is to provide a machine in which thetravel of the cutting blade and the transfer shoes are synchronized intheir relation to the receiving mechanism for the paper.

The device is simple in construction, economical to manufacture andconsists of relatively few parts, yet is highly efficient for thepurpose for which it is intended.

Other and further objects of my invention will become more apparent asthe description proceed when taken in conjunction with the drawings, inwhich:

Figure l is a perspective view of the assembled device, with the paperfed thereon from a roll.

Figure 2 is a fragmentary perspective view of a portion of the chainconveyer with the cutting blade attached thereto.

Figure 3 is a similar view of a portion of the conveyer chain having thepaper feeding shoe mounted thereon.

Figure 4 is a top or plan view of the assembled device.

Figure 5 is a fragmentary side elevation of the device as shown inFigure 4.

Figure 6 is a fragmentary cross sectional view of Figure 4 taken at theline 6-6 therein; and

Figure 7 is a fragmentary cross sectional view of Figure 4 taken at theline 7-7 therein.

Similar characters of reference indicate corresponding parts throughoutthe several views.

Referring now to details of the embodiment of the invention shown in thedrawings, 10 indicates a platform or table top which is horizontallydisposed and is supported by suitable vertical standards shown as 11supported by cross members 12. Clamps 13 and 13' are mounted along theside edges of the platform 10 for supporting shaft bearings 14 and 14 onboth sides of the platform 10. The bearings 14 and 14' rotatably supporta pair of longitudinal shafts shown as 15 and 15', spaced above theopposite sides of the platform.

Sprockets are fixed on the longitudinal shafts 15 and 15. Certain ofthese sprockets are arranged in pairs 16 and 16', 17 and 17', and 18 and18. Endless chains 19, 20 and 21 are trained over each opposed pair ofsprockets. Each chain is provided with a paper feeding shoe 22 extendingoutwardly of the orbital path of said chain. Said shoe may be made ofrubber or the like to provide a frictional bearing face, and is suitablyattached to one of the chain links as by a screw, bolt or rivet shown as23 as indicated in Figure 3.

Another chain 24 is disposed over sprockets 25 and 25' fixed on theshafts 15 and 15' near one end of the platform 10. The latter chain isprovided with a shearing blade shown as 26 suitably attached to one sidethereof ice and also extending outwardly of the orbital path of itschain, as shown in Figure 2.

One longitudinal shaft 15 has a driven pulley 27 which is revolved by abelt 28 from a drive pulley 29 on a motor 30 mounted on the floor or anyother convenient place. When the shaft 15 is revolved, the opposed shaft15' will also revolve as an idler due to the driving of the sprocketsmounted on the two longitudinal shafts; thus carrying the paper feedingshoes 22 and the shearing blade 26 in the same direction in their lineof travel.

The feeding shoes 22 are located in substantially longitudinal alignmentwith each other on their respective chains 19, 20 and 21, and insynchronized relation to the shearing blade 26 on chain 24; that saidshoes pass along the upper reaches of their chains when the blade ispassing along the lower reach of its chain, and vice versa. Thus, theshearing blade and the feeding shoes are disposed, respectively, forconsecutive non-registering movement laterally of the platform.

The extreme forward end of the platform 10 is provided with uprightbearings shown as 31 and 31 which rotatably support a transverselydisposed idler shaft 32 having upper receiving rollers 33, 33 and 33fixed there- .on which may be covered with rubber or the like to providefrictional engagement with the paper.

A pair of lower bearings shown as 34 and 34' are mounted onto the end ofthe platform 10, immediately below bearings 31, 31', for rotatablysupporting a transverse shaf 35 on which an elongated lower receivingroller 36 is fixed. This shaft 35 has a driven pulley 37 at one endactuated by a belt 38 from a drive pulley 39 mounted on a motor 40. Theupper receiving rollers 33, 33 and 33" and the lower roller 36 areadapted to have a sheet of paper indicated at 41 passing through betweenthem. This paper is taken from a roll 42 supported by a shaft 43 whichis laid on bearing yokes 44 and 44 carried on supports 45 and 45'. Asthe diameter of the paper roll 42 decreases, the paper will be carriedover the receiving roller 36 between it and the rollers 33, 33' and 33"to feed the paper over the top of the platform or table 10. Feedingmovement of the paper sheet is controlled by a limit switch 46, mountedin any convenient manner on the table top 10, depending on the length ofthe paper that is to be cut. The limit switch 46 may be of anyconventional contact-operated two-position type well known in the art,arranged to pass energizing current through motor 40 when thrown in oneposition and through motor 30 when thrown in its second position.

One side of the table has a delivery chute or slide 47 fixed therealongas shown in Figures 4 and 6. This chute is shown as downwardly inclined,terminating in curve toward the horizontal at its outer end fordelivering sheets of cut paper to the wrapping machine or the like (notshown), which is used in combination with the device.

In operation, as the machine is set into motion, the receiving rollersare revolved by motor 40 carrying the paper along the platform or tableuntil the extreme end will contact the limit switch 46, so as to switchthe current from motor 40 to motor 30. The chains 19, 20, 21 and 24 arethen put into operation and the shearing blade 26 on chain 24 will firstpass across the face of the paper. For this purpose the blade may entera transverse groove 26a (see Figure 5) in the table top to produce a cutshown as 48 in Figure 1. After the blade has passed entirely across theentire sheet the paper and the feeding shoes 22 will be brought intocontact with the top surface of the cut sheet of paper, to cause saidsheet to be laterally fed upon the chute 47 for delivery into thewrapping machine.

After this cycle of operation, the cycle may be repeated by againinitiating the feeding of the paper longichanges in the form andconfiguration of the parts may be made without departing from the spiritand scope of my invention as defined in the appended claims.
